UNDERFRAMIE FOR CARS.

specificatiori... of Letters Patent. Application filed June is, 190a. Serial No. 438,379.

To all whom it may concern:

Be known that I, ANToN' Bro-KER, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Underframes' for Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in 'underframes for cars and more particularly'to such as are supported upon the car pedestals,one object of the invention being to so construct, an underframe that it will effectually support the superstructure directly upon the car pedestals and in which A further object is to provide simple and eflicient means for connecting draft sills to a car underframe which employs no center. girder and to so construct said underframe thatit can'be mounted upon .the'pedestals' without danger of interference with the car wheels.

With these objects in view the invention consists in certain novel features in construction and combinations of parts as hereinafter set forth and pointed out in the claims. i 4

In the accompanying drawings, Figure 1 is a plan view of a portion of a car.under-. frame embodying my improvements- Fig. 2'is a" transverse sectional view on the line ww of Fig. 1. Fig. 3 is a transverse sectional viewon the line y-y of Fig. 1', and Fig. 4 is a View of a slight modification.

1, 1', represent angle beams, preferably of the'Z-type, said beams being mounted upon and secured to the car pedestals.

Between the ends of the structure, one or more cross-beams or diaphragms 2 will be located.v Each cross-beam 2 is notched or and through the medium of flanges 4 and rivets 5, are-secured to the Z-beams 1. The narrowerportions 6 of the cross-beams are disposed in a plane above that of the Z- beams and project laterally beyond the same.- The outer ends of the portions 6 of the crossject above the plane of the cross-beam and are secured to furring strips 9 seated upon the side sills, which latter are made in the form of channel-beams.

atentl Patented-Feb. 1e, 1 909. 5

,N ear the end of the structure and inprgm I I imity to'the connections of the Z-beams with 1 the pedestals, cross-beams 10 and 11 are lo .Q Q. not to interfere with the car wheels, the

cat-ed and spaced apart a sufficient distance journal boxes of which are 'm'ountedin said pedestals. These cross-beams are similar in I construction and are secured to;the Z-be'am'sfl and side sills in the same manner as the cross-beams 2 above described." The rear ends of parallel draft-sills 13-are secured to the cross-beam 11 by means of angle irons 1 .2. The ends of the side sills Tare con-' nected b a cross-beam or diaphragm 14 which is ocated at thepoint of the car end sill. The diaphragm 14 comprises two members located at respective sides of the draft sills and secured at their innerends thereto, The Z-beams 1 and the draft sills 13 project beyond the cross-beam or diaphragm 14 and are connected by means of a sill 15, thus forming aframe upon which the'car platform may be secured.

The 'cross beams 10 and 11 are provided at, their upper and lower edges with flanges, to which upper and lower cover plates'"16 and 16 are secured, said cover plates extending over and under the space between said cross: beams 10 and 11 and between the Z-beams 1. The upper-cover plate 16 is provided *with a forwardly projecting portion 17 secured centrally between its ends to the upper flanges of the draft sills. Diagonal braces 18 are secured at their. outer, forwardends, to the side si ls and cross beam 14 through the medium of gussets 19. The other ends of the diagonal braces are secured to the forwardly'projectingportion 17 of the upper cover plate 16 in proximity to the juncture of the cross-beam members 11 with the draft sills 13.

In the construction shown in Fig. 4 the side sill isarranged with its flanges projecting inwardly and to the outer face of said.

side-sill, an angle iron 20 is secured for supporting the furring strip 9. Several of these angle irons 20 may be employed and secured at intervals to each side sill. Furringstrips i 21 are disposed upon and extend across the several cross-beams,-sa1d furring strips bemg in horizontal alinement with the furring strips 9 for supporting the car floor 22. The

:side sills secured to the car sides 23 are secured to the outer faces of the side furring strips 9.

'ters Patent, is,

1. A' car underframe comprising parallel Z-beams adapted to be supported upon car pedestals, continuous cross-beams secured to and connecting the respective Z-beams and projecting laterally beyond the same, and side sills secured to the projecting ends of the cross-beams. v

2. In a car underframe, the combination with parallel Z-beams adapted to be supported upon the pedestals of a car, of crossbeams having their outer ends recessed and secured to the Z-beams at the inner ends of the recesses, the upper portions of said crossbeams projecting laterally beyond the Z- beams, and side sills secured to the projecting portions of the crossbeams.

3. In a car underframe, the combination with beams adapted to be supported upon car pedestals, of cross-beams secured to the" first mentioned beams and having portions projecting laterally beyond the latter, and projecting portions of the cross-beams.

5. In a car underframe, the'combination with Z-beams, of two cross-beams spaced apart and secured to said Z-beams, each of sa d cross-beams having portions pro ecting laterally beyond the Z-bea1ns, draft sills secured at their rear ends toone of said cross beams, a cover plate secured upon the two cross-beams and having a forwardly projecting portion, and diagonal braces securedv to the forwardly projecting portion of the cover plate and connecting the same with the forward ends of the side sills.

In testimony whereof, I have signed this specification 1n the presence of two subscrib in g Witnesses.
